This invention'relates to a liquid applying device, and more particularly to a device for applying liquid materials to articles. An object of the invention is to provide a simple and eihcient device for applying liquid material to articles.

In accordance with on embodiment of the invention there is provided a device for applying acetone to cellulose acetate coil covers to secure the covers tothe coils. The device comprises a container for holding a supply of acetone, a felt4 wick havingone end thereof partially submerged in the acetone and its opposite .end exposed for contacting the coil covers therewith,. and means 'for deecting the exposed end of the wick to vary Other features and advantages of the invenf tion will become apparent from the following detailed description when read in' conjunction with the accompanying drawing, in which Fig. l is a plan view of an acetone applying device embodying the invention;

Fig. 2 is a vertical sectional view taken online 2-2 of Fig. l;

Fig. 3 is a fragmentary front view, partly in section online 3 3 of Fig. l, and

Fig. d is a fragmentary detail section on line -t of Fig. l.

Referring to the drawing, the device illustrated comprises a horizontal supporting plate i@ having a rearwardly extending portion ii, which is suitably formed for attaching or supporting the device on a work bence or table (not shown) so that the plate iii will be positioned a suitable distance above the top of the work bench. Removably attached to the underside'oi the plate i@ is an open top receptacle or container it? having a forwardly projecting channe1-shaped lip i3 communicating with the interior of the receptacle. The receptacle is attached to the plate i@ by means of a pair of thumb screws i5, it threaded into the side edges of the plate. The shank portions oi' the thumb screws tit into open top slots i6, i@ in the upper edges of the side walls iji'i of thel receptacle. The sidewalls i'i extendahovel the rear wall and slidably engage opposite'side edges of the supporting plate andere clamped thereto by the heads of the thumb screws when the latter are'screwed into the plate. To remove the receptacle, it is necessary only to tud thumb screws suiliciently to release -their N. Y., a corporation of New .l Application December 2, 1937, Serial No. 177,755

of liquid material, such as acetone. A felt wick- 2| is provided for drawing the acetone from the 4 receptacle. The wick is supported'intermediate its endsvin thechannel-shaped lip Ilofthe receptacle so that one end of the wick extends rearwardly into the interior fof the receptacle while the opposite end of the wickA projects forwardly Ifrom the front edge of the lip. The supporting plate l0 is provided or formedl with a transverse wall or baille 23 which projects downwardly into the receptacle and serves to holdthe inner end of the wick partially submerged in the relatively small quantity of acetone contained in the bottom of the receptacle, as shown in Fig. 2. Rearward movement of the wick is limited by a pair of lugs M, 24, which project upwardly from the bottom ofthe receptacle. f

The exposed forward end of the wick lies underneath .a metal plate 255, which is plvoted or hinged-at its rear edge between a 'pair of spaced ears or lugs 26, 26 depending from opposite sides ofthe forward end of plate it. The wick is preferably composed of a felt material that has sumcient stillness, even when saturated, so that the exposed forward end thereof will normally tend to assume a horizontal position 4in line with the supported intermediate portion of the Wick. An adjusting screw 30 is provided in the forward end of supporting plate I0 amvc the hinged plate/25 so that by turning the screw in one direction the hinged plate and the exposed forward end of the wick are deflected downwardly. Thus, the exposed or applicator end oi the wich is verticallyl adjustable with respect to the level oi the acetone in the receptacle, whereby the amount of acetone that is drawn by capillary action into the exposed end of the wick or, in other words, the degree of saturationl ofthe exposed end of the wick may be varied as required.

Means is vprovided for maintaining the acetone at a constant level wi 1m the receptacle. This means comprises a cylindrical tk 32 adapted to hold a supply of the acetone. The tank is removably 'supportd Wn the plate ill, the latter having a Atubular wail. @t projecting upwardly 45 therefrom for centering the tank with respect to a circular opening Il in the plete. Threaded into the bottom o1 the tank isa discharge tube 35 'having a discharge port 36 communicating with the interior of the tank. Within thel tube a springpressed shut-on valve 38 isprovided for automatically closing the discharge port 3B when the tank is lifted from the device, for example, for the purpose of refilling it or to place it in a storerooni when the device isnot in use. The 55 valve has a depending rod 22 adapted to engage 'the bottom of the receptacle I2 and thereby effect the opening of the valve as the tank is lowered into position on the supporting plate I0.

The exterior end of the discharge tube l5 extends into the receptacle I2 to a point slightlyl above the bottom thereof, whereby only a relatively small amount of acetone is constantly creased. When the adjusting screw is turned in the opposite direction 'the exposed end o! the wick rises by reason f its resiliency and the flow of liquid is thus decreased.

. In Fig. 2, there is schematically shown in dotted lines a portion of an electrical coil 43 having a cellulose acetatefaced cover l2 partially wrapped aroundthe The'cover is qi' sufiiclent length toprovide overlapping end portions. As shown in the drawing, the inner surface of the outer end portion of the cover is pressed-lightly liquid thereto.

against the exposed end of the felt wick 2|' to receive a coating of acetone which causes the overlapping end portions of the cover to adhere rmly to each other when pressed together.

It is to be understood that the invention is not limited to the particular construction and embodiments herein illustrated and described, ex-

cept insofar as is deiined by the appended claims.

What is claimed is:

1. A liquid applying device comprising a liquid containing receptacle, a wickl having one end partially submerged in the liquid and its opposite end extending exteriorly of the receptacle. a hinged plate for controlling the position of the exterior end of the wick, and an adjusting screw for shifting the plate to change the position of said exterior end of the wick to thereby vary the ilowoftheliquid thereto.

2. A liquid applying device comprising a support. -a liquid-containing receptacle suspended from said support, a' wick having one end parltially submerged in the liquid and its opposite end projecting laterally from the receptacle, a plate pivotally suspended from said support and in contact with the upper surface of the laterally projecting end of the wick, and means for angularly shifting said plate to deilect the projecting end of the wick and thereby vary the flow of JOHN S.
